However, some password kits can figure out the original password from encode file. Namely, many encoded files are really accessible even if you forget their passwords.

Comments

When you get these resources, you should understand everyone can get them too. In other words, if encrypted files of yours are copied to others. Even if they don’t have passwords, they probably can open these files by some password tool kits. Especially for files created by old specifications, it’s easy to download free kits to reverse the password and then open them.

So, we don’t recommend setting password for individual file. One reason is the owners forget passwords from time to time and are compelled to give up the data. On the other hand, as long as data thieves get these files, they have lots of options to dig out the contents.

In the general, the file password is just a temporary method to lock file. Because the encryption algorithm heavily relies on computing capability, it’s safe only if your computers are powerful enough and with new operating system. Meanwhile your software has to be upgraded to the latest versions and updated with all patches.

We give you two rules here regarding to file password.
  • If your computer and software aren’t updated to mainstream level, don’t trust file password, even if it’s a fleeting usage.
  • If the file is used to record data for future reference, don’t use password to lock it, because after 2 or 3 years it should be relatively easy to decode today’s encryption.

In general, you should be cautious to use file password. In case you applied it before but forget it somehow, we hope resources here can help you recover your password and get your data back.
